Late night sewer back up
Steve - Crystal Lake, IL
Dan was at our house within 45 minutes. Took care of the problem. Super friendly and he taught me a few things in the process. Very reasonable price for a late night emergency call.
Great service as always

Black diamond is my go to for any electrical needs I have. Our tech Rick was awesome and again is why I only use Black Diamond!
Craig - Crystal Lake, IL
We’ve used black diamond for a few years on all hvac needs. We’re always satisfied. This time our tech went above and beyond. Our home humidifier has “needed to be replaced” for a couple years. To me it’s never been worth the $900 fix to replace it. Yesterday the tech was at our home for a prepaid hvac maintenance. He recognized the humidifier wasn’t working and decided to figure out why... after some electrical investigation he found the problem and fixed it. Because of his experience and work ethic he basically saved me $900. I’ve been told by around 5 other techs that it wasn’t working and would cost me $900 to fix it. Tech: Nick C.

Disappointed in not receiving our 5% discount for being club member. Also in the way it was left after the job was finished.
Eric - Crystal Lake, IL
Fixed a leaking outside spigot in 5 F temps, and saved us from a burst pipe in the basement too during the inside inspection. We call Black Diamond every time.
Outstanding Emergency Service
Judi - Crystal Lake, IL
Juan Munoz was at my house in a matter of 20 minutes. He took care of the problem immediately and was polite, patient, professional and personable. He went above and beyond to fix the problem and help with the water mess. Excellent service.
Excellent service; always very satisified with technical expertise.

Response time is incredible considering all the people that probably have crisis problems in their homes around the same time that I may be calling in.
Awesome service rep.

Joe - Crystal Lake, IL
Overall it was a great experience. Set up appointment day before and got all the work done the following day. We had a billiard light installed and other home improvement electrical work done. Very professional and efficient and pleasent to deal with!
Doug - Crystal Lake, IL
We originally called Black Diamond about a water leak coming from our Bryant 560. David Fajardo was sent to handle for BD. David did a great job in explaining where and why the unit failed. His professionalism was refreshing ( and he is a Dodger fan. Just like us). Thanks again!
Jesus was polite and very helpful
Sandra - Crystal Lake, IL
I would be glad to have Jesus respond to any calls I have to Black Diamond and he is the main reason for my continued patronage of your company.
Love Black Diamond.
